Could have not cut the domes right for the crank possibly.

anyway, ship that engine out and have a sponsor

gonthrough it. If it needs domes pistons etc you'll have enough

Like gusto said sounds like the head wasn't set up for the longer stroke crank. Pull the head off and the jugs and see what the head, pistons, and rods look like and take pictures and we can go from there. It's all going to depend on what's broke...... thats a good looking bike lets get her running!

Also where are you from? There might be someone close that would be willing to help you

Were the cylinders ported for the 4 mil? If the head wasn't cut i wouldn't be surprised if they didn't port the cylinders. It might be cheaper and easier at this point to go back to stock.

Im from the Fresno area. I found a mechanic that is going to take a look at it.

Here are some images of the banshee and some parts.

Get better pics of the cylinders. Flip em up aide down and get a pic also the bore. Also the tops of the pistons, side of the crank rods and domes.
Looked like the transfers had been ported from what i could see, could see too well

Update, took it to a mechanic and just off first sight he could of tell the cylinders were messed up and top end might of blown due to the port.

 

Now my question is should I just buy the parts and leave it at 4 mil or convert it back to stock. Don't really care for speed. I just want it to be reliable and less chance it could mess up again.

Look into prices and see what u want to set your budget at. If you want to stay cheep on the build I have a stock stroke crank in good shape if yours is in good shape I'll trade you. Or you could sell the crank and buy a stock. How bad are the cylinders? Try to take a good picture of inside the bore. Of both cylinders

i left the Banshee with the mechanic so he can inspect it some more. So I cant take the pics at the moment.

Is having everything stock more reliable than having it with the 4 mil?

Reliability really all depends on quality of parts and work done on built. But most importantly tuning. Maby someone else will chime in and say otherwise but if it's built right and tuned right and well maintained they will both last just as long, depending on how you ride.


But on your 4 mil to have it built correctly you need to find a reputable builder send your cylinders off and have them probably bored out if there trashed and then ported for the 4 mil. Plus the correct pistons for the stroke, a new head if that one is trashed and correct domes cut for the 4 mil stroke ur builder will tell you what to get or sell it to you. Plus jetting your carb out for the 4 mil. Check out our sponsors and check prices call builders and see what they recommend.

not really.  if the machine is put together properly and setup right, it should be reliable.  who did you take it to?

imo you really need to be taking this stuff to someone who SPECIFICALLY deals with banshees, in my experience that is where you will get the best results from.

If it were me, if the crank and bottom end is good I would have the cylinders bored to the next size assuming your not at 66.5 bore, new pistons, cylinders ported for the 4 mil stroke, and have some stroker domes cut for your head..  This should all be done by a site sponsor sir.
